Patent CA-2435321-A1 (CA)
Inventor: CRASS MATTHEW D
IPC: G01R31/74
Filed: 2003-07-16
Abstract: In one form, tester for an electrical system, such as for a vehicle, develops repetitively applied, short duration, control current pulses for reducing load current pulses through the electrical system. An operator connects a pair of input contacts across a fuse holder. A circuit between the input contacts is closed momentarily and repetitively to produce repetitive current pulses from the electricity source through the system. A perceptible alert is produced when the magnitude of the current pulse exceeds that of a prescribed reference current value. In another form, a tester for an electrical system is designed to plug into the fuse terminals in a fuse box.  The tester can include a plurality of interchangeable circuit breaker modules to allow the tester to be used on circuits having differing current ratings.

Abstract: A means is described of connecting multiple flexible printed circuit (FPC) tags. The means is suitable where electrical circuitry has been printed or otherwise applied to one side of flexible substrates, and where the circuitry of two such substrates is required to be brought into electrical continuity. In this method, a sewing, stitching or embroidery machine is used to hold juxtaposed conductive surfaces in electrical continuity by tension. In a variation of the means, conductive thread, wire or other material is used to create an electrically-conducting via between the relevant conductive surfaces of two ar more such i=PC tags.

Title: System and method for noninvasive hematocrit monitoring
Inventor: HARRIS DAVID B
IPC: G01N33/49
Filed: 1993-04-12
Abstract: A system for determining the hematocrit transcutaneously and noninvasively. Disclosed are a finger clip assembly (6) and an earlobe clip assembly (10), each including at least a pair of emitters (1,2) and a photodiode (3) in appropriate alignment to enable operation in either a transmittion mode or a reflectance mode. At least two, and preferably three, predetermined wavelengths of light are passed onto or through body tissues such as the finger (7), earlobe (11 ), or scalp, etc. and the extinction of each wavelength is detected. Mathematical manipulation of the detected values compensates for the effects of body tissue and fluid and determines the hematocrit value. If a fourth wavelength of light is used which is extinguished substantially differently by oxyhemoglobin and reduced hemoglobin and which is not substantially extinguished by plasma, then the blood oxygen saturation value, is determinable independently of the hematocrit value. It is also within the scope of the present invention to detect and analyze multiple wavelengths using a logarithmic DC analysis technique. In this embodiment, a pulse wave is not required. Hence, this embodiment may be utilized in states of low blood pressure or low blood flow.

Title: A method, apparatus and system for multiple signal transmission, reception, and restoration
Inventor: SENDYK ANDREW M
IPC: H04B7/02
Filed: 2003-11-18
Abstract: Techniques for increasing the capacity of a radio link, using radio signal superimposing in space and frequency and subsequent signal restoration, are described. Each of the transmitting and receiving systems are connected to a plurality of collocated antennas. The signals that are superimposed are recovered by one or a plurality of restorers. The disclosed method of signal processing involves appropriate filtering of signals, then summing them in order to restore the original individual signals and to cancel out all undesired signals received as a result of superimposing. Preferably, the spacing between antennas is optimized so that while the undesired signals are minimized or canceled out, the restored signals are maximized. In simple situations, signal filtering may be reduced to phase adjustment of the signals and the restoration may be done at RF, IF  or baseband. In more complex situations, general adaptive filters implemented in baseband may be preferred. Various embodiments of the restorer are presented.

Patent CA-2459963-A1 (CA)
Inventor: NG EDDIE KAI HO
IPC: H04B10/08
Filed: 2004-03-02
Abstract: A method and system for multi-level power management in an optical network is provided. They include three levels of power management. The first level of power management dynamically changes equipment settings in each module of equipment so that required module setpoint values in each module are achieved. The second level of power management determines module setpoint values for each module of equipment within each node in the optical link so that required node setpoint values are achieved. The third level of power management determines node setpoint values at each node in the optical link so that the optical link meets predetermined power specifications. If any of the three levels cannot achieve the required setpoint values, an error signal is generated by that level of power management and sent to the level of power management above it, thus initiating a higher level of power management. As a result, a dynamic and automatic adjustment to changing operating conditions and configurations in the network is provided, which allows to maintain relatively stable network powers. Each level of power management is implemented such that sections of the network can operate independent of each other, thus increasing the survivability of the network.

Abstract: A two-jawed trap including a cable snare encircling spring-loaded jaws when the trap is set. When the rap is sprung, it is constructed to disconnect the spring from the jaws under load from the animal making desperate forcible attempts to release the trap, thus allowing the jaws to open from the leg of the animal. However, the snare is set at the same time that the trap is sprung, so the animal remains caught by the snare even though the trap rigid frame including the jaws releases and completely detaches from the animal leg.
